(running frequency) is adjusted to the working status of oil transfer pump after system PID arithmetic, according to the judgement of main oil transfer pump running frequency value
Carry out automatically engaging and cutting out for auxiliary pump.
In host computer setting or oil transportation flow or pressure under remote mode, or set on the touchscreen in local mode
Oil transportation flow or pressure is put to be carried out according to the flowmeter or pressure of the oil transportation pump discharge collected to PLC controller, PLC controller
PID arithmetic, then PLC controller output running frequency value, frequency converter, frequency converter output voltage are sent to by MODBUS communications
Frequency adjusts the speed of service of main oil transfer pump, so that oil transportation flow reaches setting oil transportation flow.
Main pump cuts out auxiliary pump and hauls oneself willingly into：After main oil transportation pump startup oil transportation flow has reached setting oil transportation flow, and it is less than
After cutting out running frequency and continuing sometime, after main oil transfer pump is freely shut down and cut out.Small flow auxiliary oil transfer pump at the same time
Operation is automatically engaged, system reaches oil transportation flow and stablize setting according to the operating status of feedback flow adjustment auxiliary pump
Oil transportation flow (or pressure).
Auxiliary pump cuts out main pump and hauls oneself willingly into：When aiding in oil transfer pump oil transportation, system adjust automatically oil transfer pump running frequency, output
Flow (or pressure) is from motion tracking setting flow (or pressure), and output flow still can not reach after oil transfer pump reaches full speed running
To after continuing sometime, small flow auxiliary oil transfer pump autostop is cut out, and main oil transfer pump automatically engages, system adjust automatically master
Oil transfer pump running frequency, makes oil transportation flow (or pressure) reach setting flow (or pressure) and stablizes.
Can so be set according to different output oil amount, system automatically between big flow oil transfer pump and small flow oil transfer pump from
Dynamic switching.
The above is not intended to limit the invention, for the skill of this area only to the preferred embodiment of the present invention
